Method for winding coil on an object

Abstract

A method for winding a coil on an object, wherein the coil includes a plurality of first coils and a plurality of second coils, may have winding the first coils on an exterior circumferences of the second coils, wherein an outer circumferences of the respective second coil is enclosed and in contact with outer circumference of at least three first coils, and wherein cross-sectional area of the second coil is smaller than that of the first coil, and wherein the outer circumference of the at least three first coils are in contact each other.

What is claimed is: 
     
       1. A method for winding a coil on an object, wherein the coil comprises a first coil and a second coil, cross-sectional area of the second coil being different from cross-sectional area of the first coil, the method comprising:
 winding the first coil on an exterior circumference of the object or the second coil such that cross-sectional centers of a plurality of first coils form a row; and 
 winding the second coil on the first coil such that cross-sectional centers of a plurality of second coils form a row, 
 wherein winding the first coil and winding the second coil are repeated by predetermined numbers such that a plurality of rows of the first coil and the second coil are wound on the object or the second coil, and 
 wherein the cross-sectional centers of the first coil and the second coil are disposed to form a zigzag shape with each other. 
 
     
     
       2. The method of  claim 1 , wherein the cross-sectional centers of the first coils are disposed to form a plurality of columns vertically disposed to the rows. 
     
     
       3. The method of  claim 2 , wherein (m,n), (m,n+1), (m+1 and n+1), and (m+1,n) cross-sectional centers among the cross-sectional centers of the first coils are disposed to form a square, and
 wherein m and n are any natural numbers, and a (m,n) cross-sectional center means a cross-sectional center of the first coil disposed at an intersecting point of a m-th row and a n-th column. 
 
     
     
       4. The method of  claim 3 , wherein the cross-sectional area of the second coil is smaller than that of the first coil, and
 wherein each cross-section of the second coil is disposed in a pore formed among the (m,n), (m,n+1), (m+1 and n+1), and (m+1,n) cross-sections of the first coil. 
 
     
     
       5. The method of  claim 4 , wherein the cross-sectional area of the second coil is approximately 17% of or smaller than that of the first coil. 
     
     
       6. The method of  claim 1 , wherein a current of the first coil flows in an opposite direction to that of the second coil. 
     
     
       7. A method for winding a coil on an object, wherein the coil comprises a first coil and a second coil, cross-sectional area of the second coil being different from cross-sectional area of the first coil, the method comprising:
 winding the first coil on an exterior circumference of the object such that cross-sectional centers of a plurality of first coils form a row; and 
 winding the second coil on the first coil such that cross-sectional centers of a plurality of second coils form a row, 
 wherein winding the first coil and winding the second coil are repeated by predetermined numbers such that a plurality of rows of the first coil and the second coil are wound on the object, and 
 wherein the cross-sectional centers of the first coil and the second coil are disposed to form a zigzag shape with each other. 
 
     
     
       8. The method of  claim 7 , wherein the cross-sectional centers of the first coils are disposed to form a plurality of columns vertically disposed to the rows. 
     
     
       9. The method of  claim 8 , wherein (m,n), (m,n+1), (m+1 and n+1), and (m+1,n) cross-sectional centers among the cross-sectional centers of the first coils are disposed to form a square, and
 wherein m and n are any natural numbers, and a (m,n) cross-sectional center means a cross-sectional center of the first coil disposed at an intersecting point of a m-th row and a n-th column. 
 
     
     
       10. The method of  claim 9 , wherein the cross-sectional area of the second coil is smaller than that of the first coil, and
 wherein each cross-section of the second coil is disposed in a pore formed among the (m,n), (m,n+1), (m+1 and n+1), and (m+1,n) cross-sections of the first coil. 
 
     
     
       11. The method of  claim 10 , wherein the cross-sectional area of the second coil is approximately 17% of or smaller than that of the first coil. 
     
     
       12. The method of  claim 7 , wherein a current of the first coil flows in an opposite direction to that of the second coil.
